FILLER FOR COMPRESSION GREASE-GUNS.

Specification of Letters Patent.

Patented Feb. 10, 1920.

Application filed August 11, 1919. Serial No. 316,753.

To all whom/t lmuy concern.'

Be it known that I. lVILLnxM CARL Ir'rionk, a citizen of the UnitedStates, residing at Vatts, in the county ot' Los `Angeles and State ofCalifornia, have invented new and useful Improvements in Fillers forCompression Grease-Guns, et which the following is a specification.

My invention relates to improvements in devices for ijilling grease.guns and the like and the objects of my invention are to ino vide ailling meansfor a grease gun which will put a charge of hard grease intothe, gun casing in almost solid form eliminating practically all airpockets. a 'second object being to provide means tor filling a greasegun that is quick and cleanly in its operation.

Figure l is a perspective view of the filler partially entered into agrease gun casing., the easing being shown in section.

Fig. 2 is a fragmentary sectional view of the filler fully entered intoa grease gun casing.

Fig. 3 is a top View of the filler with a handle ren'ioved and a greasegun 'asing Fig. 4 is an outer end view ot the filler showing a method oflling the filler with a proper paddle. n' carrying ont my invention acylindri- .cal easing A is provided having one of its ends open and aclosure fixed in the other end and extending therefrom forming anadequate, handle H. The casing A also has a slotin its wall running fromend to end and disposed longitudinally. Within the casing is fixeda-piston con'iprising a cup leather E positioned against a plate N beingheld h v a Washer P and a screw I.

The plate N has an integral lug extending outwardly through the slot inthe casing A. Pivotally connected tothe lug by the rivet V is a hook F,the hook being disposed away from the casing A. so that the casing ot agrease gun may. be slipped between the hook F and casi ln the operationof' the device the piston E is first carried backwardly to the inner endof the easing A. by n'xanipnlating the hook F. Grease is then filledinto the cas piston, as set forth herein in its ing. '.lCl'iit'l maydifferent ways but such a"s`1s shown in place successive plugs of greaseinto the gun against the piston E the paddle being operated with thehandle extending from the longitudinal -slot in the casing.

When the casing is filled with grease it is then inserted into a greasegun casing. The grease gun casing is then grasped with one hand with thefore-finger engaging the hook l1". The handle H is then taken in handand the Casing A withdrawn from the grease gun casing leaving acylindrical deposit of hard grease within the gun. The piston E is thenreturned to the bottom of the filler and it is again ready for use.

Various changes might be made in the structure of the device and theform of the referred form. without departing from t e spirit thereof asclaimed.

I claim:

1. A filling device for grease guns cone.

. prising a cylindrical casing having a longitudinal slot. a pistonslidably mounted in the easing, a handle connected withthe pis tonthrough the slot whereby the piston may be held while the casing iswithdrawn from a grease gun casing.

2. A Filling device for grease guns comprising a cylindrical casinghavingsa longitudinal slot, a piston slidably .mounted in. the casinghaving a the slot,` a hook pivotally connected to the lug whereby thepiston may he held While the casing is withdrawn from a grease guncasing.

3. A filling device 'For grease guns comprising a cylindrical casinghaving a longitudinal Slot, a closure for one end ot the casing andextending therefrom forming a proper handle, a piston slidably mountedin the casing having a lug extending through the slot, a hook pivotallyconnected to the lug whereby the piston may be held while the casingiswithdrawn from a grease gun casino'.
